Inpatient omission of ACEi and ARBs is associated with morbidity and mortality in COVID-19

ABSTRACT:

Purpose

Due to the affinity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for the human angiotensin converting enzyme 2 (ACE2) receptor, use of angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) has been a major concern for clinicians during the 2020 pandemic. Meta-analyses have affirmed that these agents do not worsen clinical outcomes in SARS-CoV-2 infection. To date, only a limited number of studies have directly looked at the safety of inpatient prescription of ACEi/ARBs during acute COVID-19 illness.

Methods

A retrospective cohort analysis was conducted to investigate the impact of inpatient provision of ACEi/ARBs on morbidity and mortality in patients admitted to hospital with COVID-19. Relationships were explored using linear and logistic regression.

Findings

Six hundred and twelve adult patients met our inclusion criteria of which 151 (24.7%) patients were established on ACEi/ARBs. Despite correction for known confounders, discontinuation of ACEi/ARBs was highly predictive of worsened outcomes in COVID-19. The proportion of doses omitted in hospital was significantly associated with increased mortality (p<0.001, OR=9.59 [2.55-36.09]), maximum National Early Warning Score (NEWS-2; p<0.001, OR=1.66 [1.27-2.17]), maximum oxygen requirements (p<0.001, OR=3.00 [1.83-4.91]), and maximum C-Reactive Protein concentration (CRP; p=0.030, OR=1.83 [1.06-3.17]).

Implications

Our data demonstrates a strong association between missed ACEi/ARB doses with increased morbidity and mortality. The available evidence supports continuation of current accepted practice surrounding ACEi/ARB therapy in acute illness – which is to limit drug omission to established acute contraindications, to actively monitor such decisions and to restart therapy as soon as it is safe to do so.

Project description:Aims and objectives: The pandemic of COVID-19 is evolving worldwide, and it is associated with high mortality and morbidity. There is a growing need to discuss the elements of a coordinated strategy to control the spread and mitigate the severity of COVID-19. H1N1 and Streptococcus pneumonia vaccines are available. The current analysis was performed to analyze the severity of COVID-19 and influenza (H1N1) vaccination in adults ≥ 65. Also, to correlate the lower respiratory tract infections (LRIs), and influenza attributable to the lower respiratory tract infections' incidence with Covid-19 mortality. Evolutionarily influenza is close in resemblance to SARS-CoV-2 viruses and shares some common epitopes and mechanisms. Methods: Recent influenza vaccination data of 34 countries from OECD and other publications were correlated with COVID-19 mortality from worldometer data. LRIs attributable to influenza and streptococcus pneumonia were correlated with COVID-19 mortality. Specifically, influenza-attributable LRI incidence data of various countries (n = 182) was correlated with COVID-19 death by linear regression and receiver operating characteristic (ROC) curve analyzes. In a logistic regression model, population density and influenza LRI incidence were correlated with COVID-19 mortality. Results: There is a correlation between COVID-19-related mortality, morbidity, and case incidence and the status of influenza vaccination, which appears protective. The tendency of correlation is increasingly highlighted as the pandemic is evolving. In countries where influenza immunization is less common, there is a correlation between LRIs and influenza attributable to LRI incidence and COVID-19 severity, which is beneficial. ROC curve showed an area under the curve of 0.86 (CI 0.78 to 0.944, P < 0.0001) to predict COVID-19 mortality >150/million and a decreasing trend of influenza LRI episodes. To predict COVID-19 mortality of >200/million population, the odds ratio for influenza incidence/100,000 was -1.86 (CI -2.75 to -0.96, P < 0.0001). To predict the parameter Covid-19 mortality/influenza LRI episodes*1000>1000, the influenza parameter had an odd's ratio of -3.83 (CI -5.98 to -1.67), and an AUC of 0.94. Conclusion: Influenza (H1N1) vaccination can be used as an interim measure to mitigate the severity of COVID-19 in the general population. In appropriate high-risk circumstances, Streptococcus pneumonia vaccination would also be an adjunct strategy, especially in countries with a lower incidence of LRIs.

Project description:ObjectivePregnancy involves dynamic changes in the maternal immune system, thus potentially affecting women's response to infection. The aim of this study was to investigate whether gestational age at the time of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with mortality and morbidity related to coronavirus disease 2019 (COVID-19) in hospitalized pregnant women.MethodsThis was a cohort study of pregnant women with confirmed SARS-CoV-2 infection at any gestational age (categorized into trimesters) who were hospitalized in Brazil from February 2020 to November 2021. Sociodemographic and epidemiological characteristics, signs and symptoms, comorbidities, interventions, vaccination status and type of healthcare establishment were obtained from a nationwide database. Multivariate logistic and Cox regression analyses were used to identify independent risk factors for in-hospital COVID-19-related mortality and morbidity (defined as time from hospital admission to recovery).ResultsA total of 7461 SARS-CoV-2-infected pregnant women were included in the study (9.3%, 28.4% and 62.3% in the first, second and third trimesters, respectively). After adjustment for sociodemographic, epidemiological and clinical characteristics, and intervention-related variables, gestational age at infection was found not to be associated with COVID-19-related mortality and morbidity. Women admitted to establishments with an obstetric center, compared to hospitals without, were 38% less likely to die from SARS-CoV-2 infection (adjusted odds ratio, 0.62; 95% CI, 0.48-0.80), while patients who received private not-for-profit healthcare had a 13% shorter time to recovery (adjusted hazard ratio, 1.13; 95% CI, 1.07-1.20) compared to those who received public healthcare.ConclusionsDespite a higher percentage of women being admitted in the third trimester, we found no association between gestational age and COVID-19 mortality and morbidity. The previously reported increase in morbidity and mortality in the third trimester in pregnant women with COVID-19 may be attributable to other gestational-age-affected variables for which adjustment was made in our study. © 2022 The Authors.
